例子

VBA：

Sub Example_TrueColor()
    ' This example draws a line and returns the RGB values
    Dim line As AcadLine
    Dim startPoint(0 To 2) As Double
    Dim endPoint(0 To 2) As Double
        
    startPoint(0) = 1#: startPoint(1) = 1#: startPoint(2) = 0#
    endPoint(0) = 5#: endPoint(1) = 5#: endPoint(2) = 0#
        
    Set line = ThisDrawing.ModelSpace.AddLine(startPoint, endPoint)

    Dim color As AcadAcCmColor
    Set color = line.TrueColor
    color.SetRGB 80, 100, 244    
    line.TrueColor = color

    ZoomAll

    Dim retcolor As AcadAcCmColor
    Set retcolor = line.TrueColor
    
    MsgBox "Red = " & retcolor.Red & vbLf & _
           "Green = " & retcolor.Green & vbLf & _
           "Blue = " & retcolor.Blue
End Sub

    ;; This example draws a line and returns the RGB values
    (setq acadObj (vlax-get-acad-object)
          doc (vla-get-ActiveDocument acadObj))
  
   
    (setq startPoint (vlax-3d-point 1 1 0)
          endPoint (vlax-3d-point 5 5 0))

    (setq modelSpace (vla-get-ModelSpace doc)
          line (vla-AddLine modelSpace startPoint endPoint))
    
    (setq color (vla-get-TrueColor line))
    (vla-SetRGB color 80 100 244)
    (vla-put-TrueColor line color)

    (vla-ZoomAll acadObj)

    (setq retcolor (vla-get-TrueColor line))
    
    (alert (strcat "Red = " (itoa (vla-get-Red retcolor))
                   "\nGreen = " (itoa (vla-get-Green retcolor))
                   "\nBlue = " (itoa (vla-get-Blue retcolor))))
